always use /etc/os-release and ignore all distro-specific files

The text mode welcome message will only show the distro name stored
in /etc/os-release and no longer read any distro-specific files.  If
/etc/os-release does not exist, 'Linux' will be printed.

When the source tree is is ./configure'd, only /etc-os-release is read
to guess the distro to build for. If /etc/os-release does not exist,
--with-distro= needs to be specified.
